Step-by-step explanation:

The (a) & (b) will be answered by making reference to the attachment.

Solving (a): Time to reach maximum height

The height is plotted at the vertical axis while the time taken is at the horizontal axis.

From the attachment; the following details can be observed

Using function notations, this can be represented as:

And the interpretation is that:

Peter's baseball reached the maximum height at 1.5 seconds

Solving (b): Time to hit the ground

The interpretation of this question is to solve for the x intercept of the graph.

From the attachment; the following details can be observed

Using function notations, this can be represented as:

And the interpretation is that:

Peter's baseball hit the ground at 4 seconds

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.
